AI Technical Summary
Technical Problem
The existing molding machines require manual sand to be sent into the sand cylinder, which is very labor-intensive and wastes time. The sand is easily moist and clumped, affecting the sand blasting effect.
Method used
A sand-loading device for boxless molding machines is designed, including components such as storage box, servo motor, transmission shaft, mixing rod, heating rod and feed pipe. The servo motor drives the transmission shaft and mixing rod to stir and heat the sand to prevent agglomeration and moisture blockage.
Benefits of technology
Automatic sand conveying and processing is realized, reducing labor intensity and time of manual operation, preventing sand from getting damp and agglomerating, and improving the efficiency and effect of sand blasting.

Abstract
The utility model discloses a sand feeding device for a flaskless molding machine. The sand feeding device comprises a storage box, according to the device, sand is conveyed into the storage box through the sand conveying pipe, the transmission shaft is driven by the servo motor to rotate, the caked sand is smashed through the stirring rod arranged on the transmission shaft, and meanwhile the sand at the bottom in the storage box can be driven through the first auger arranged on the transmission shaft; and meanwhile, a heating rod is started to heat the sand in the storage box, so that the sand is prevented from being moist to block the discharge port, and the sand in the storage box is stirred and heated, so that the sand is prevented from being moist and agglomerated to block the discharge port, and the discharge port is prevented from being blocked. Sand is discharged through a discharging port after being stirred and heated and then enters a conveying pipe through a feeding hopper, a one-way motor drives a second auger to convey the sand, and meanwhile the height of the conveying pipe is adjusted through a rotating shaft, a screw and a sleeve arranged on the surface of the bottom of an output pipe.
